Human-Machine Interface
Smart Cockpit and HMI
The number of processors, sensors, memory, and other electronic components applied in automobile cockpits is increasing daily. These new features reduce the risk factors of driving behavior. The HMI subsystems connected to vehicle buses leverage connectivity and autonomous driving technologies to enhance driving safety, prioritizing reliability and predictability.
Meanwhile, the smart cockpit is also an evolving concept. Future automotive cockpits will feature more diverse application scenarios as autonomous driving progresses, such as long-distance driving and commercial vehicles that will drive innovations in smart cockpit design.
Our Services
Mechatronic Solution Provider
In recent years, the integration of electronic functionalities in vehicle development, such as safety support and convenience features, has driven the growth of HMI solutions. HMI products aim to enhance user satisfaction not only through functionality and design but also by offering compact and intuitive operational methods accessible to everyone.
AdvantagesCollaborating with OEM manufacturers to develop new automotive components. These products include complex new firmware features and higher-level safety requirements implemented through rigorous development processes, such as DFMEA. Products are designed with safety strategies in mind, considering the stability and protection of electronic modules in various automotive scenarios to prevent potential accidents.
Automotive HMI-Related Products
We provide a variety of automotive HMI-related products, such as electronic shifters (joystick type, rotary type, paddle type, stalk type), multifunctional steering wheels (capacitive, vibration feedback, heating functions), multifunctional knobs, smart key entry systems, touch panels, and steering wheel HOD (Hand Off Detection), all of which have been implemented in mass-production vehicle models.
Automotive HMI Systems and Functional Safety
For most HMI systems, the safety integrity level reaches ASIL B, and in some cases, even ASIL C. For example, steering wheel touch buttons used for cruise control functions or touchpads must meet ASIL B/C levels. Failure modes include detecting unintentional increases in cruise control speed via touch input.
Reliability Testing Services and Equipment
With the emergence of innovative products surpassing traditional concepts, hybrid electronic HMI products require extensive evaluation equipment to ensure high-level performance and quality. This includes equipment for testing vibration resistance, weather resistance, water resistance, and sensitive technologies like ambient lighting or interior lighting color evaluation.
Electromagnetic Interference (EMI) and Compatibility (EMC)
The density and complexity of electronic product circuits bring challenges in meeting EMI (Electromagnetic Interference) and EMC (Electromagnetic Compatibility) standards for automotive regulations. We provide professional services in this area, guided by hardware design consultancy teams and ISO 26262 experts, to develop CISPR, ISO/IEC-compliant hardware solutions for automotive product development projects.
